So WX is 7y +4 and XY is 21, and when you add those lines you get the whole thing, which is 12y so write that like an equation
12y = 7y+4+21
12y = 7y+25
5y = 25
y = 5
Answer:
8 1/2
Step-by-step explanation:
Change the denominators so they're the same 1/3 equals 2/6. 1/6 +2/6 is 3/6 and 5 + 3 is 8. Simplify to get 8 1/2
Answer:
The integral is the probability that the tire will fail in at some point between 26000 and 32000 miles.
Step-by-step explanation:
Consider the provided integral.
It is given that the tires are guaranteed to last for 30,000 miles, but some will fail sooner and some will last many more miles beyond 30,000.
And f(L) be the probability density function for the random variable L.
According to the probability density function (PDF):
The PDF is used to determine the likelihood of a random variable falling within a specified range of values.
Thus, the integral:
Gives us the integral is the probability that the tire will fail in at some point between 26000 and 32000 miles.

Answer:
The value of x is 12
Step-by-step explanation:
4x3=12
7x3=21
Therefore 12/21
To explain further:
If you divide 12 by 3 you get 4
If you divide 21 by 3 you get 7
Therefore resulting to 4/7
(I found out that the number three goes in both numbers to begin with)
Is this clearer?
